I noted here the recent discovery in the Golan Heights of the Byzantine-era church built over a Pan sanctuary. This is the first I have heard of the inscribed altar.
Derelict stone buildings have typically been dismantled and the stones reused in antiquity and even more recently. Here in St. Andrews, the ruins of the cathedral were scavenged for stones after it was ransacked by John Knox and his friends. The stones are scattered around the town in other stone buildings.
